[White-coat and masked hypertension]

ALFÖLDI Sándor

[White-coat hypertension is a heterogenous clinical entity, that includes patients with lower and higher cardivascular risk. Its prognosis is relatively benign, when it is not associated with other cardiovascular risk factors. Therefore, cardiovascular risk evaluation has utmost importance in patients with white-coat hypertension for the determina­tion of appropriate treatment. Masked hy­per­tension, however, is not a benign pheno­type, as it has been proven. Its early recognition, regular follow-up and effective anti­hypertensive drug treatment are mandatory. ]

[The role of acupuncturists’ qualifications in randomized controlled trials of acupuncture]

ORAVECZ Márk, MÉSZÁROS Judit, YU Funian, HORVÁTH Ildikó

[BACKGROUND - Randomized controlled trials (RCT) of acupuncture show heterogeneity in several ways. Acupuncture interventions used for the same conditions are greatly variable and so are study designs. METHOD - We evaluated the most frequently cited randomized controlled trials of acupuncture based on traditional Chinese medicine by examining practitioner background using elements of the “STandards for Reporting Interventions in Clinical Trials of Acupuncture”. The extracted data was compared with international guidelines and standards of traditional Chinese medicine and acupuncture education. RESULTS - We identified 5 heterogenous educational systems with contact training hours ranging from 120 to 3000. The educational criteria set by 93.75% of the reviewed trials did not meet the standards of the World Health Organization guidelines for acupuncture education or the World Federation of Chinese Medicine Societies standard for Chinese medicine education. Education in traditional Chinese acupuncture is internationally heterogeneous and this heterogeneity was found to be underreported in 87.5% of these trials, not provided for in study design. DISCUSSION - The generalizability and external validity of the reviewed trials may be questioned regarding the participating practitioners’ training background. In the future, a similar evaluation of systematic reviews could help further elucidate the issue of educational heterogeneity in traditional Chinese medicine acupuncture trials.]

[The effect of anesthesia on cognitive functions]

BOCSKAI Tímea, KARÁDI Kázmér, BURIÁN András, KOVÁCS Norbert, BOGÁR Lajos, LUJBER László

[Aim of the study - General anesthetics, arterial hypotension and hypoxia developing during anesthesia may result in impaired memory and a decline in other abilities (such as attention, concentration, linguistic and writing abilities). Our aim was to detect changes in cognitive functions due to surgery and anesthesia with controlled arterial hypotension. Materials and methods - We studied combined and intravenous anesthesia detecting pre-and postoperative cognitive functions, intraoperative haemodynamic parameters, demographic data, other data of case history and surgical data. The Montreal Cognitive Assessment test was applied in the randomized, prospective study. The preoperative data served as basis for comparison. The second test was performed following surgery when patients were fully awake. Both groups included 30 patients. Results and conclusion - After both narcosis methods (postoperative second hour) cognitive functions were significantly deteriorated (p<0.05). Median MoCA before sevoflurane anesthesia was 24 points (interquartile range: 22-25), postoperative value was 20 (19-21) (p<0.05). Median MoCA before propofol anesthesia was 24 points (23-26), postoperative value was 20 (18-22) (p<0.01). Intraoperative arterial blood pressure, pulse rate and oxygen saturation values did not correlate with worsening of cognitive function (Pearson correlation coefficient values between -0.19 and 0.42). Execution is influenced by age (negative correlation) and education (positive correlation).]

[SOME ETHICAL DILEMMAS OF PLACEBO-CONTROLLED STUDIES]

KOVÁCS József

[The article deals with the question where and when is it ethically acceptable in a randomized controlled clinical trial to give the investigational drug to one of the groups, while placebo to the other. First, it gives a short overview on the origin of the problem and the history of its reemergence before and after the revision of the Declaration of Helsinki 2000. It examines the various forms of placebo use, the pros and cons of its implementation, the international debate before the revision of the Declaration of Helsinki 2000 and the corrections after its acceptance. Finally it declares some principles in connection with placebo controlled clinical trials and examines when such a trial is acceptable in various psychiatric disorders.]

[Primary prevention program of the Hungarian Spine Society - Part II Controlled prospective study of short term efficacy]

SOMHEGYI Annamária, TÓTH János, MAKSZIN Imre, GARDI Zsuzsa, FESZTHAMMER Artúrné, DARABOSNÉ Tim Irma, TÓTHNÉ Steinhausz Viktória, TÓTHNÉ Szabó Klára, VARGA Péter Pál

[Introduction - The primary prevention program of the Hungarian Spine Society is set around 12 test exercises that assess performance of postural muscles and then develops their strength and flexibility. By this the scheme aims to make the biomechanically correct use of the spinal column spontaneous. Subjects and methos - The application of the scheme in the frame of physical education in a primary school was investigated in a prospective controlled study in the school-year of 2001/2002. Participating children were aged 6 to 14. The intervention group (n=200) regularly did the posture correction exercises with their teacher's direction in physical education classes, while the control group (n=213) did not. The 12 test exercises of the posture correction scheme of the Hungarian Spine Society were tested by an independent physiotherapist at the beginning and at the end of the school-year in both groups. Results were analyzed by paired and unpaired t-tests and by a chi-square test. Results - At the end of the school-year the strength and flexibility of the postural muscles of the intervention group improved significantly compared both to their own performance (p<0.01) at the beginning of the school-year and to the control group. Test results of the control group were significantly (p<0.05) worse at the end of the school-year than their own results at beginning of the school-year, and were more significantly (p<0.01) worse than the test results of intervention group. Conclusion - The results of the controlled study confirm that regular use of the preventive exercises in physical education improves the strength and flexibility of postural muscles. In order to analyze the results concerning specific muscle groups or age groups a detailed study with age- and gender-matched controls will be necessary.]

[ASTHMA THERAPY ACCORDING TO THE REVISED INTERNATIONAL RECOMMENDATION]

HERJAVECZ Irén, BÁNKÚTI Beáta, CSOMA Zsuzsanna

[A comprehensive workshop report entitled “A Global Strategy for Asthma Management and Prevention - Global Initiative for Asthma (GINA)” first published in 1995, has been widely adapted, translated and reproduced, and forms the basis for many national asthma guidelines. The 2006 report contains important new themes. It asserts that it is reasonable to expect that in most patients with asthma, control of the disease can be achieved and maintained, and recommends a change in approach to asthma management with asthma control, rather than asthma severity, being the focus of treatment decisions.]

[Haemophilia today]

KARDOS Mária

[Haemophilia is the most well-known inherited bleeding disorder, which has an X-linked inheritance and affects men. Its severity is classified on the basis of the amount of circulating functional clotting factors: patients with values < 1% have severe disease, those with values of 1-5% have moderate disease, and those with values >5% are classified as having mild disease. Severe haemophilia is characterised by frequent, spontaneous bleeding episodes, whereas in those with moderate or mild haemophilia, bleeding is only caused by trauma or surgery. Although bleeding can occur almost anywhere, the most common clinical manifestation is haemarthrosis. Haemophilic arthrpathy that develops as a result of repeated episodes of joint haemorrhage is the most important factor of morbidity in those with haemophilia. Intravenous replacement of the missing clotting factor is used to treat and prevent bleeding episodes. Controlled therapy at home that provides immediate replacement is the optimal early approach. Prophylaxis includes administration of clotting factors at regular intervals to prevent bleeding, which must be the main goal of management until a cure becomes available. The development of inhibitors during treatment is the most significant complication of factor replacement, and management of bleeding in patients with such inhibitors is difficult.]

[LATE EFFECTS OF TREATMENT FOR DECREASING CARDIOVASCULAR RISK “CARDIOMETABOLIC THERAPEUTIC MEMORY” - A HYPOTHESIS]

JERMENDY György

[In several randomised, controlled clinical studies conducted to decrease cardiovascular morbidity and mortality, there was long-term observational follow-up after the termination of the double-blind phase. There is evidence that the beneficial effect of the therapeutic intervention in the active study phase was maintained in the follow-up period. This phenomenon was observed both for life-style modification and for pharmacological intervention, including the use of ACE-inhibitors, statins, fibrates and intensive insulin treatment. This fact suggests the possibility that even after several years, the body “remembers” the beneficial effects of the cardiovascular risk reduction achieved years earlier. The phenomenon may be called “cardiometabolic therapeutic memory”.]

[Examination of leukocyte-endothel interactions in inflammatory animal models]

GONDA Andrea, MIKECZ Katalin, HUNYADI János

[Leukocyte influx into tissues is one of the hallmarks of physiological reactions to inflammatory stimuli, which is followed by a multistep process, resulting in leukocyte extravasation from the postcapillary venules. The different kinds of adhesion molecules, that play role in the rolling and firm adhesion of the leukocytes, have been investigated very intensively. By the help of animal models of inflammation, numerous individuals, being in the same stage of the disease, can be examined. The requirement for the adhesion molecules for inflammatory responses could be investigated with antibodies or, nowadays more often, gene knock out (KO) or transgenic mice. Beside evaluating the morphological and cytokine profile differences, using intravital microscopy is of great importance in the inflammatory experiments, while it allows observing interactions of virtually any blood cell types with the endothelial wall in vivo. The results are sometimes conflicting, indicating that the process of leukocyte-endothel interactions depends on different kind of other factors than the adhesion molecules, and still not fully understood.]
